摘　　要：文章利用灰色系统的关联分析,把湿陷变形看成是一个多因素作用的、多因素关联的、整体的、非线性的灰色系统,从密度、孔隙比、含水量等普遍存在影响的一些土性天然状态的指标因素的影响来探讨黄土的湿陷变形的一些影响因素,从而可以为湿陷变形的建模分析提供一些参考依据,也可为黄土地基湿陷变形相应的工程评价提供某些依据,同时,也说明了灰色关联分析这一方法在分析湿陷变形方面适应了黄土湿陷变形的非线性本质。At the basis of analysis on influencing factors of collapsibility of loessal foundation, it is subjected that the collapsibile deformation should be thought of as a system that many factors worked and influenced together , especially a grey system.. Thus the grey incidence analysis method can be applied to collapsibility of loessal foundation, and it is cheerful that the method works so well that some useful results could be attained according to the grey incidence analysis on influencing factors of collapsibility of loessal foundation, results indicat that the void ratio is the superior and steadily influencing factor of collapsibility at all events and other influencing factors will have some different degree of influence . The paper expounds some influencing factors of collapsibility and helps to think eorrectly some influencing factors in setting up the model of collapsibility.
